What explanation is there to shoot an old grandfather playing a video game on a phone in a parked vehicle? Go on, I'm listening.
Well, you don't know for a fact what he was doing when this happened. Age and having kids/grandkids or not doesn't actually define whether someone getting shot is justified or not.
Going by the info that there were shots going in the front windshield and a side window, it could be the guy drove at the security guard and he fired at the guy.
All I'm saying is that people see a headline, and a brief piece of information and jump through all kinds of comments about convict this guy, jail, murder, etc., without knowing WHY the guard shot this man.
Whether that's justified or not is up to the courts.
